Grease penetration measurement [1]. This can be solvent molecules, more complex polymeric structures, small particles, gas bubbles, etc.

A brief presentation of the globally used ASTM test is given below: E937 and petrolatum The consistency of grease from almost fluid to semi-fluid to hard can be measured in a range up to Penetration Units.

Bitumen testing in a water bath. Type text as it appears:: The inner structure is characteristic for each material and can be influenced by outside forces as well as the ambient conditions.

ASTM D937 – 07(2012)

Cover four procedures for measuring the consistency of lubricating greases by the penetration of a cone of specified dimensions, mass and finish. Email Us or call toll-free: The ambient condition that influences the consistency most is the temperature. The value is obtained by calculation from needle penetration and the ring-and-ball softening point using a softening point tester.

Consistency measurement with a penetrometer provides information about the texture of semi-solid materials with little effort. The penetration test provides information on the texture.

The deeper the cone sinks into the material, the softer the sample and the lower the consistency.

The treatment in a grease worker exposes the sample to high mechanical stress in a comparatively short time. Consistency describes the degree to which a semi-fluid or semi-solid material resists deformation by an applied force.

Lab Equipment for Sale: Definition of consistency Consistency describes the degree to which a semi-fluid or semi-solid material resists deformation by an applied force.

A brief presentation of astk globally used ASTM test is given below:. Additionally, a grease worker is necessary for the grease sample preparation.

Koehler K Penetrometer (ASTM D5, D, D, D, D, D, D) | Labequip

ASTM D aztm Roll stability of lubricating grease Covers determination of the changes in the consistency, as measurably cone penetration, of lubricating greases when worked in the roll stability test apparatus.

We come across consistency all the time in everyday life without even thinking about it. Using this value, conclusions can be drawn about the performance of bitumen as a binder for road construction.

However, if a substance is too liquid it may run off the bread slice. A fluid liquid has no such yield point. Koehler K Penetrometer Condition: Product Description This Koehler K penetrometer is designed for ASTM penetration tests on petroleum products and for consistency tests on a wide range of food products, cosmetics, pastes and wstm solid to semisolid products.

Consistency gives food the typical mouthfeel that is experienced when it is swallowed. General Use laboratory apparatus balances, baths, blenders, centrifuges, chart recorders, freezers, fume hoods, furnaces, glassware washers, glove boxes, mixers, moisture testing, ovens, pumps, shakers, vacuum equipment, water purification ASTM Method being used?

A sstm example of consistency determination is the penetration measurement of grease. The harder more solid the material, the smaller the cone angle should be. Difference between fluid, semi-solid, and solid materials Fig.

This test method is applicable to waxes having a penetration of not greater than
